Material blocking is a common failure of crushing machinery and equipment. In the production process of crushing machinery and equipment, once the material is blocked, the equipment will be forced to s and affect production efficiency. So, what is the reason for the damage of the counterattack crusher and how to deal with it? The following are the reasons and solutions for the blocking phenomenon of the impact crusher.

1. The material has high humidity and high viscosity
If the water content of the raw material is large and the viscosity is large, the crushed material will easily adhere to the sides of the sieve holes and the lining plate, resulting in a reduction in the volume of the crushing cavity and a decrease in the sieve hole passing rate, * to material blocking.
Solution: You can preheat the impact plate and feed inlet, install drying equipment, or insulate the material to reduce the moisture in the material.

2.Fast feeding speed
When the impact crusher feeds too much and the speed is too fast, it is too late to crush and discharge, * to blockage.
Solution: Pay attention to the deflection angle of the ammeter pointer during feeding. When the feed is large, the pointer that breaks the ammeter will be too large. When the rated current of the machine is exceeded, overload operation will result. In this case, too long a working time will cause the material to block or even burn the machine's motor. On the one hand, when this happens, it is necessary to immediately reduce the amount of feed and adjust it by adjusting the feeder.

3. Equipment runs slowly
In general, the feed speed and the discharge speed are balanced. Too fast feeding speed will lead to blockage, while too slow unloading speed will also cause a large amount of material to block the inside of the machine, which will cause blockage and prevent the equipment from working properly.
Solution: In order to avoid overloading the machine, adjust the feeding speed according to the processing capacity of the machine; adjust the size of the discharge opening in time according to the actual situation of the production, so that the crushed materials are discharged smoothly. If the crushed material changes, the size of the discharge port should be adjusted accordingly.

4. The particle size of the conveyed material is too large, and the hardness of the material is high
When the hardness of the material is large, it is not easy to break, or the particle size of the feed exceeds a large range limited by the impact crusher. When there is not enough crushing Solution: Before the material enters the crushing cavity, the applicable materials of the impact crusher should be clarified, especially the requirements of the material properties to ensure that the crusher is correctly entered; it is not easy to put too much material into the crushing cavity. An electric bell and an alarm light can be installed at the feeding port to control the feeding and avoid clogging too much material. After coarsely crushing a large piece of material, put it into the crushing cavity to make the material reach or approach crushing as much as possible. Need to avoid material blocking.

5. Equipment parts are severely worn
If the main components of the impact crusher wear out, the crushing effect of the material will also cause blockage.
Solution: Pay attention to check the wear of the components, and replace the severely worn components in time to ensure the crushing effect of the material and reduce the blockage of the material.

6. The V-belt is loose and the driving kinetic energy is insufficient.
The crusher relies on a V-belt to transfer power to the trough to achieve the purpose of material crushing. If the V-belt is too loose, it will not be able to drive the trough, affecting the crushing of the material or preventing the broken material from being removed smoothly. Cause clogging.
Solution: During the production process, please pay attention to check the tightness of the V-belt. If not, please adjust in time.

7. Counterattack broken spindle damage
If the spindle is damaged, all parts of the equipment will be involved and will not operate properly, which will s the equipment from moving and cause material blocking.
Solution: operation and maintenance personnel need to pay more attention to the maintenance and repair of the spindle, timely lubrication, good maintenance, and timely solve problems to avoid affecting normal production.

8. Improper use
Part of the cause of the blockage is operator error, which may be unfamiliar with the process or temporary errors.
Solution: Equipment operators must undergo rigorous training to qualify. Not only must they be familiar with the operating specifications of the equipment, they must also understand the process of the entire production line.
